GRIDVERT Generate grid vertex adjacency map.
[ V, VV ] = GRIDVERT( C, INDC, N_SDIM ) Generates an sparse map V which indicates which cells are connected to each other through the nodes.
Input Value/(Size) Description  c (n_v,n_c) Cell connectivity pointer array where the entries in each column correspond to the cell vertex numbers specifying the cells. indc vector Index to cells for which to compute map (all cells by default). n_sdim scalar Optional input argument indicating computation. of connectivities for connected edges. . Output Value/(Size) Description  v sparse(n_c,n_c) Sparse array indicating which grid cells are connected through the grid points. Or with three input arguments a which grid cells are connected though the edges (incl. n_sdim). vv sparse(n_p,n_p) Sparse array which for each row indicates which nodes/edges are connected through cells.
